METHOD OF LIQUID SPRAYING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC B05B17/06 

FIELD: technological processes.

SUBSTANCE: in method of liquid spraying ultrasonic oscillations of higher mode are excited in oscillating system of transducer-concentrator by introduction of ultrasonic oscillations into liquid layer. Then they are resonantly transformed into double-sided longitudinal oscillations in concentrator neutral part. Then sprayed liquid is introduced to one or two working butt ends of concentrator. Device for method implementation includes annular piezoelectric transducer and concentrator. Transducer represents annular piezoelectric cell. Concentrator includes double-staged cylindrical section and double-staged conical section installed in it. In cylindrical section internal stage has larger thickness than the external one. In conical section conical stages form deepening. Opening is provided along concentrator axis, which is connected with liquid-supplying tube by radial opening. External cylindrical surface of concentrator is rigidly connected to internal cylindrical surface of piezoelectric cell.

EFFECT: possibility to prepare fine-dispersed aerosol.
